Manual maize flour milling machine

Types of manual maize flour milling machines

A manual maize milling machine processes maize into flour by hand. They are smaller and more affordable than electric models, which makes them ideal for rural settings without electricity. Some basic and common machines used for milling maize manually are:

• Maize Milling Machine with Hand Crank

  This simple design has a milling mechanism, a hopper, and a hand crank attached to the side. The user pours dry maize into the hopper, and the maize is milled as the crank is turned to rotate the milling device. The hand-cranked maize milling machines come in various sizes and models. Some models have adjustable settings to allow the flour to have different textures from coarse to fine. Other models come with grinding stones instead of steel blades. The grinding stones make less noise and produce finer flour. No special skills are required to operate the milling machine with a hand crank. Manual maize milling machines with hand cranks are slow, and the operator can only mill a small amount of maize at a time. They are suited for home use where a small quantity of flour is needed.'

• The Lever-Operated Maize Mill

  This milling machine processes maize by operating a lever. It has a frame, hopper, milling component, and lever. The maize is fed through the hopper and into the milling chamber. A crosswise lever moves back and forth to push the pestle, which crushes the maize. Older models use the wind as the primary source of energy. Newer ones use animal power and have a pulley connected to an animal such as a donkey.

  Using the lever is easier than cranking since the lever moves in a shorter range. Like the hand-crank models, the lever-operated maize mills are best for small scale maize milling.

• Portable Manual Corn Mill Grinder

  This grinder is small enough to carry from one place to another. It is ideal for home use and emergency preparedness since users can store it and carry it anytime. It uses a crank handle, which is similar to the hand-crank milling machines discussed above. However, it is smaller in size and more portable. The grinders are made from metal and cast iron, and some have noise-reducing technology.

• Integrated Maize Milling Machine for Home Use

  Some manufacturers design milling machines that also have a purification or separation system. These integrated systems also come with a high extraction rate and an energy-efficient design.
